Chirip
"The Chirip Peninsula, jutting NW-ward into the Sea of Okhotsk from central Iturup Island, is constructed of twin overlapping Holocene stratovolcanoes. Chirippusan (also simply Chirip) volcano on the north and Minami-Chirippu (also called Bogdan Khmelnitskii) on the south overlie a pre-glacial volcano, rising above a 1100-m-high saddle to 1561 and 1587 m, respectively. Lava flows from both edifices are truncated by a large, 4-km-wide depression on the west side of the peninsula. Basaltic rocks dominate at both volcanoes over basaltic-andesite and andesitic products. Chirippusan has a shallow summit crater, partially filled by a small lake, that has fed lava flows down all sides; satellitic cones are located on the northern flank. Lava flows from Minami-Chirippu (or South Chirippu) reach the coast on both the east and west sides. Only two 19th-century eruptions are known in historical time, the last occurring in 1860 from a vent SE of the summit of Minami-Chirippu."  -Smithsonian Volcano Archive
